摘要：

The presence of adventitious oxygen in the reaction of [(Triphos)MoCl3] (Triphos = Ph2PCH2CH2P(Ph)CH2CH2PPh2) with NaSeC6H2Me3-2,4,6 in THF leads to the formation of [fac-MoO(Ph2P(O)CH2CH2P(Ph)CH2CH2PPh2)(SeC6H2Me3-2,4,6)2]. This is the first example of a structurally characterized molybdenum(IV)oxo-selenolato complex. It contains a chelating triphosphine mono-oxide ligand. The formation can be understood in terms of an oxidative addition of dioxygen to the metal centre followed by oxygen atom transfer to the triphos ligand and reduction of molybdenum to molybdenum(IV).
